2、2 I FOREWORD The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecom- munication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunicatio
3、ns on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. ITU-T Recommendation 4.786 was revised by the ITU-T Study Gr
4、oup XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993). NOTES 1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T)
5、was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector. In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms “CCITT, CCIR or IFRB” or t

9、 Q.786 SIGNALLING SYSTEM No. 7 SCCP TEST SPECIFICATION (Helsinki, 1993) 1 Introduction This Recommendation contains a detailed set of tests for the Signalling System No. 7 Signalling Connection Control Part (SCCP). These tests are intended to validate the protocol specified in Recommendations 4.711-
10、4.714. This Recom- mendation conforms to Recommendation 4.780, which describes the basic rules of the test specification. 2 Objective of the test specification The objective of the test specification is to provide: Validation - A level of confidence that a given implementation conforms to the Recomm
11、endations 4.71 1-Q.7 14 for SS No. 7 SCCP. Compatibility - A level of confidence that two implementations of SS No. 7 SCCP are able to interwork. In order to ensure that this test specification meets this objective, the following criteria are used: 1) 2) 3) The test specification is not intended to
12、provide exhaustive testing of all aspects of the SS No. 7 SCCP. All tests should be of a practical nature and implementable using the available technology. The test should concentrate on the testing of a normal signalling procedure. Testing of an abnormal signalling procedure will only be identified
13、 where this is regarded as particularly useful. The test list does not include any tests which are application specific (e.g. IN, mobile application, etc.). If such tests are required, they should be contained in application specific testing documentation. 4) 3 Scope of the test The test list is com
14、posed to validate routing/addressing and data transfer concerning connectionless SCCP procedures by monitoring and analysing SCCP messages and their contents. SCCP management, segmentation in connectionless SCCP test and connection-oriented procedures are for further study. Some tests in this Recomm
15、endation require generation of primitives, therefore when performing these tests, appropriate normal system action of the user will have to be chosen which results indicating primitives being generated. The testing of primitives is outside the scope of this Recommendation. Both messages and primitiv
16、es are shown in expected message sequence diagram as indicated below, but primitives are shown for ease of understanding only. . An internal routing of SCCP user data is implementation dependent, and therefore all tests related to internal routing may not be possible to execute. In addition, access
17、to various test interfaces may not be available in all implementations. Recommendation Q.786 (03/93) 1 ITU-T RECflN*Q.78b 73 = 4862571 0584184 141 b b SP C SP A 4 4 4 General principles of tests The tests are described as “Validation(VAT)” tests or “Validation” and “Compatibility(CPT)” tests. Each t
18、est description indicates in the field “type of test” whether the test is a “Validation” test or a “Validation” and “Compatibility” test. All questions and checks in the test description should be answered with positive acknowledgement for correct operations. Where particular failure conditions are
19、tested with or without the return option set, the test with the return option not set should use the same pre-test conditions and data, with the exception of the return option parameter as the corresponding test with the return option set. Some of the described validation tests may not be required t
20、o be executed, since the functionality they aim to test is not included in the Implementation Under Test (IUT). In such a case the non-execution of such a test should not be regarded as a non-conformance statement. For the test cases which result in returning N-NOTICE indication primitive or UDTS me
21、ssage, N-UNIDATA request primitive or UDT message should include the sufficient information to return the N-NOTICE indication primitive or UDTS message. SP B 5 Test environment 5.1 SCCP relation A signalling relation is required between “SP A” and “SP B” or among “SP A”, “SP B” and “SP C” in order t
22、o carry out effective tests. Tested MTPs should be used for compatibility tests. 5.2 Configuration Two configurations are required to perform these tests as shown in Figure 1 and Figure 2. I sp .
